Description
The Blynk IoT Heart Rate and Oxygen Monitor Kit is an Internet of Things (IoT)–based health monitoring project that measures real-time pulse rate and blood oxygen (SpO₂) levels using the MAX30100 sensor. The readings are processed by an ESP32 microcontroller and transmitted to the Blynk mobile application for remote monitoring. This project introduces learners to biomedical sensing, IoT communication, and data visualization through cloud platforms.
Key Features
- Real-time monitoring: Continuously measures heart rate and oxygen saturation (SpO₂).
- Cloud connectivity: Sends data to the Blynk IoT app for live display and remote tracking.
- Wireless communication: Utilizes ESP32’s built-in Wi-Fi module for seamless data transmission.
- Compact and efficient design: Requires minimal wiring using jumper wires for quick setup.
